As I know the most people would be available at 20:00 CET, please write who may be able to start tomorrow at 15:00 CET.

I know it would look like only 5 people will start at 15:00 and the rest at 20:00 (what would cause launching 2 servers), but maybe we would avoid it if more people will be available earlier (of course, I don't want to force you for anything).
